Metar history

The IEM maintains an ever growing archive of automated airport weather observations from around the world! A more generic term may metar history METAR data, which is a term that describes the format the data is transmitted as.

Metar Please select the metar date, cycle time, then insert the 4-letter ICAO code for every airport separated by a space, then select the output format. If you select "txt" you will get a simple txt output of the metars directly downloaded from the NOAA website. If you select the "pdf" format you will get a formatted and paginated metar list in a pdf sheet.

Metar history

METAR is a format for reporting weather information. In its publication the Aeronautical Information Manual , the United States Federal Aviation Administration FAA describes the report as aviation routine weather report , [1] while the international authority for the code form, the World Meteorological Organization WMO , describes it as the aerodrome routine meteorological report. METARs typically come from airports or permanent weather observation stations. Reports are generated once an hour or half-hour at most stations, but if conditions change significantly at a staffed location, a report known as a special SPECI may be issued. Some METARs are encoded by automated airport weather stations located at airports, military bases, and other sites. Some locations still use augmented observations, which are recorded by digital sensors, encoded via software, and then reviewed by certified weather observers or forecasters prior to being transmitted. Observations may also be taken by trained observers or forecasters who manually observe and encode their observations prior to transmission. The WMO's publication No. A typical METAR contains data for the temperature , dew point , wind direction and speed, precipitation , cloud cover and heights, visibility , and barometric pressure. In the United States, the code is given authority with some U.

This is well over half a billion reports and counting, making it to our knowledge the largest publicly available archive of its kind. A very convenient way to keep track of weather at your home airport or usual destination is to use your regular XMPP-based chat service, such as Quicksy or Blabber. From your chat application, add a contact such as zzzz wx. You may subscribe directly from the results page by clicking on the icon for the desired station. A link is also available from the results page when you make a data request. Within reason, it is OK to gather up as much data as you need for your own use. What you are not allowed to do is redistribute the data without acknowledging the source.
